Synopsis

Keywords: Synthetic MR, Head & Neck/ENT, Differential diagnosis

Motivation: The presence of metastatic lymph nodes in HNSCC indicates a worse prognosis, biopsy is invasive and has a high incidence of false-negative results. The diagnosis value of synthetic MRI needs to be studied further.

Goal(s): To explore the value of the features derived from synthetic MRI in distinguishing between benign and malignant lymph nodes.

Approach: This study included lymph nodes of HNSCC which were confirmed by pathology, and utilized multiple methods to select meaningful features.

Results: Features derived from synthetic MRI have satisfactory discrimination efficiency.

Impact: Synthetic MRI may be able to be used as a method to help assemnet the lymph nodes in clinical practice.
